Hi all,
I have met a problem about oil pressure switch. Anyone have an oil pressure switch that’s installed but not connected? Found this while trying to track down a small oil leak in my new to me ‘99 10AE. There isn’t even a wire in the area to connect it. I think it’s the source of the leak...
All modes of SGL8022W are toggle mode, ie every time you need a touch to switch off or on.
Is there a way to make it into a momentary switch, where default is off and on touch it fades in and it fades out when touch is removed?
Hi everyone,
I am currently a rising senior majoring in computer engineering. I wasn't able to secure an internship this summer so I wanted to come up with ideas for projects.
One of my project ideas is creating a police speed gun that uses LIDAR to measure the speed at which a vehicle is...
Hi everyone. I am junior level electronics hobbyist and I'm hoping to get some help designing some kind of voltage switch for an automotive application.
Precisely what I am trying to do
Detect if the DC voltage on a circuit is above or below a certain threshold (say 1.0V) with reasonable...
Hi Folks,
just completed a course on creating a webserver using an Arduino Uno which allows for remotely monitoring and controlling actuators. This also includes visualizing the sensor data on really cool looking animated dials... Based on what I've learned (and I really learned a lot), I...
Hello Community!
During My project of "removing motion artifacts from the PPG signal" I faced many problems related to the pulse sensor that it didn't give me any good signal, and it is for commercial use, that's why I decided to build the sensor and replace it with an electronic circuit using...
I am now starting to test the wall vibration experiment, which requires a large number of vibration sensors. I have some doubts there:
1. Do these sensors need to be affixed to the wall, can they be affixed directly with tape?
2. Are there any particulars about the distribution of sensors?
3...
I am a student from mechanical background in my final year of college with a little knowledge of sensors and circuits and need a few ideas to solve this problem.
There exists a brass tube something of this sort as shown in image in which oil would be immersed, with a metal ball inside and the...
hello every one for a project i need to work with a line sensor TCD1304 AP .
here it's the data sheet link http://www.spectronicdevices.com/pdf/TCD1304AP.pdf
i don't know what's the exactly protocol of this sensor
how i should use this ? what kind of processor i should use ? will a esp 32...
Hi, first time poster here and electronics beginner. I wonder if anyone can answer a question or two few ...
As a follow-up to this post: the gentleman wanted to create a circuit to control a strip of LEDs along his driveway using a motion sensor at both ends. I have been looking for advice on...
I am going to start a project where I need to check that if the cricket ball is hitting on a particular area on ground second the speed of this cricket ball. I need one solution which can fulfill my two demands.
For this, I need a large area(200mm x 200mm)sensor with low power consumption and...
Hello,
My name is Daniela, I'm student and I need help to anyone who can help me :D
Project goal: Control the temperature inside a closed chamber
I need help to connect the all components and I don't know how because I'm new in this .
I don't know how to amplify and to maintain the current...
The problem I'm facing is how can I verify the measured data is it correct or not?
And whether the sensor will give any value in Zeros or not?
Below is the file in which I'm getting data packets but mostly the values are the same every time.
I'm designing a tracker for assets. I want your suggestions to implement into the circuit a method to detect when someone is trying to remove the tracker. I was thinking of surrounding the board with touch pads all around the edges of the board but I guess that would be very sensitive to noise...
Hello everyone
My name is Mauricio, I'm new in this forum.
I am student of the first semester , so I do not know that much about electronics, I got really interested in this kind of topics and I am trying to make some little projects for the microcontrollers PIC using assembler coding.
I have...
I need help designing a circuit to control a servo motor, the model i have is an SG 90 (9g) It needs to be controlled by a sensor that receives and input from a moving object, (the object moves down), and the sensor reads the signal 1 -> 2 the servo moves up 120deg, (the object moves up) and...
I am using the accelerometer to detect the vibration but at the same time, I need to test the free-fall detection using wireless sensor with Arduino https://store.ncd.io/product/mma7660fc-3-axis-orientationmotion-detection-sensor-%C2%B11-5-g-accelerometer-i2c-mini-module/ and perform some...
is there a way to distinguish between daylight and artificial light in a room? I'm thinking my options are a light intensity sensor or a color temperature sensor. The sunlight is supposed to be much stronger than artificial light. But I'm wondering if the case will be the same inside a room. Or...
